1. According to the selection of control function, each valve has its own function, please pay attention to its corresponding function when selecting.
2. According to the selection of working conditions, the technical parameters of common valves include nominal pressure, maximum allowable working pressure, working temperature and medium. When selecting, it should be noted that the above parameters of working conditions are consistent with the technical parameters of the valve.
3. Select according to the installation structure. The installation structure of the pipeline system includes pipe screws, flanges, ferrules, welding, hoses, etc. Therefore, the installation structure of the valve must be consistent with the installation structure of the piping, and the specifications and dimensions must be consistent.
When the medium flows through the copper valve, pressure loss will occur, that is, the copper valve has a certain resistance to the flow of the medium, and the medium will consume a certain amount of energy to overcome the resistance of the copper valve. In order to save energy, when designing and manufacturing the copper valve, the resistance of the copper valve to the flowing medium should be reduced as much as possible. The opening and closing force and torque refer to the force or torque that must be applied to open or close the copper valve.
